Traveling patterns of neuronal activity—brain waves—have been observed across a breadth
of neuronal recordings, states of awareness, and species, but their emergence in the human …

Microglia interact with neurons to facilitate synapse plasticity; however, signal (s)
contributing to microglia activation for synapse elimination in pathology are not fully …

The rapid developments in functional MRI (fMRI) acquisition methods and hardware
technologies in recent years, particularly at high field (≥ 7 T), have enabled unparalleled …

Purpose fMRI is the convolution of the hemodynamic response function (HRF) and
unmeasured neural activity. HRF variability (HRFv) across the brain could, in principle, alter …

Understanding how one brain region exerts influence over another in vivo is profoundly
constrained by models used to infer or predict directed connectivity. Although such neural …

Understanding the spatial dynamics of dilation in the cerebral vasculature is essential for
deciphering the vascular basis of hemodynamic signals in the brain. We used two-photon …

Large-scale dynamics of the brain are routinely modelled using systems of nonlinear
dynamical equations that describe the evolution of population-level activity, with distinct …

Neural processes are complex and difficult to image. This paper presents a new space-time
resolved brain imaging framework, called Neurophysiological Process Imaging (NPI), that …

The gray matter of human cortex is characterized by depth-dependent differences in
neuronal activity and connections (Shipp, 2007) as well as in the associated vasculature …

Granger causality (GC) and dynamic causal modeling (DCM) are the two key approaches
used to determine the directed interactions among brain areas. Recent discussions have …
